简介 [Problem] When plating a rare earth magnet, components of the rare earth magnet dissolve in a plating solution, causing plating defects. A simple method for removing the rare earth impurities has been required. [Solution] An electrolytic nickel plating solution in which rare earth impurities dissolve is heated up to 60 °C or more and this temperature is maintained for a certain time, thereby allowing the rare earth impurities to form deposits, which are separated by sedimentation and filtration. Alternatively, by adding the deposits to the electrolytic nickel plating solution or by heating and concentrating the electrolytic nickel plating solution, it is possible to more efficiently precipitate the rare earth impurities.
